Infrared detector
First Claim
1. An infrared detector comprising:
- a detecting element comprising a carbon nanotube layer divided into an absorbing part and a non-absorbing part, a first end located in the absorbing part, and a second end located in the non-absorbing part, wherein the absorbing part is configured to absorb infrared, and the carbon nanotube layer is a free-standing and continuous structure;
a first electrode electrically connected with the first end;
a second electrode electrically connected with the second end; and
a covering structure covering the non-absorbing part, to prevent the non-absorbing part from absorbing infrared, and exposing the absorbing part;
wherein the absorbing part is exposed through a plurality of through holes spaced from each other.

Abstract
An infrared detector includes a detecting element, a first electrode, a second electrode, and a covering structure. The detecting element defines an absorbing part and a non-absorbing part. The detecting element includes a first end and a second end opposite with the first end. The first end is disposed in the absorbing part. The second end is disposed in the non-absorbing part. The first electrode is electrically connected with the first end. The second electrode is electrically connected with the second end. The covering structure covers the non-absorbing part. The detecting element further includes a carbon nanotube layer. The carbon nanotube layer includes a plurality of carbon nanotubes disposed uniformly.
